Figure 3: Monolithic planar retroreflector made of two metasurfaces. Figure 5: Characterization of the wavefront and polarization modifications by the retroreflector. For a given substrate thickness, ...

Sometimes the most enlightening experiments also happen to be the simplest. Conceptually, at least. A small array of instruments headed to Mars — in addition to one already there — holds the potential ...

NASA’s Lunar Reconnaissance Orbiter has been shooting lasers at Japan’s Smart Lander for Investigating Moon (SLIM) in an attempt to hit a retroreflector mounted right beneath the lander’s solar panels ...

Aiming Earthbound lasers at the lunar retroreflectors is a bit like "using a rifle to hit a moving dime 3 kilometers away," say scientists. Halfway to Mars, NASA’s Perseverance Rover is carrying an ...

Using information provided by NASA’s Lunar Reconnaissance Orbiter (LRO) instrument teams, researchers at the University of California, San Diego, have successfully pinpointed the location of a ...
